Many Markham homes still run on 60A or 100A service that simply was not built for EV chargers, heat pumps, induction ranges and home offices. We upgrade panels to 200A, replace fuse boxes with modern breaker panels, and coordinate every step with ESA so your service has the capacity Markham households now need.
Panel Upgrades in Markham: local know-how
Older properties near Main Street Markham and Unionville frequently have 60A or 100A service and sometimes original fuse panels, while even some 1990s subdivisions in Berczy and Cornell are now maxed out. Adding a Level 2 EV charger, a cold-climate heat pump, or a basement suite often tips a panel past its limit. We upgrade services to 200A, swap fuse-to-breaker panels, install new grounding and bonding to current code, and add capacity and dedicated circuits for the loads you're planning. A panel or service upgrade is notifiable work in Ontario, so we file the ESA permit, coordinate the utility connection where needed, and arrange the inspection.
